I have two ideas for you, though spawned of the same seed, one is Serious, and the other is a little more Silly.
Loyalty Is,
Missing posters are stuck to sign posts. Fallen pages litter gutters. People go missing all the time, the Lost know this more then most. An old emaciated Wizened women comes to Funderland clutching a stack of photocopies. Someone dear to her has gone missing, no one's taken their place, but still she worries. Will the Freehold look into it, just to make sure?
Mission Impawsible
A mother is worried about her son! He's obviously fallen into a ruff crowd! Lured in by those ill bred mongrels, wagging their tails, for shame! It's only a matter of time before her precious boy's picked up by those horrible hairless bipedal snatchers!
A little bit silly, a little bit strange. The worried mother is a doggish hob, and her son seems to have wandered away from the Hedge and into the Mortal world. She bids you find her son before animal control finds him.
